1. PREDICTION OF COAL SLURRY PIPELINE TRANSPORTATION GRADING REDUCTION AND ITS INFLUENCE ON PIPE TRANSPORTATION PARAMETERS
Abstract Coal slurry pipe, being a new type of energy transportation mode, changes of the particle composition and the effect on other parameters are worth studying. Comparison of ring tube test measured data and batch grinding model simulation data shows that batch grinding model can predict the coal particle gradation to a certain extent. The effect of col

2. Analysis of a car door subjected to side pole impact
Abstract The results of a study on the response of a side impact beam located in a car door to impact loading is presented. The side impact beam is situated in both the front and rear side doors of a vehicle between the inner and outer shells to minimise intrusion into the passenger compartment during a collision whilst absorbing as much impact energy as pos

3. The Effectiveness of Thin-Walled Hull Structures Against Collision Impact
Abstract The impact phenomenon is one of many subjects that is interesting and has become an inseparable part of naval architecture and ocean engineering fields. Limitless possibilities in cause and scenario make the demand to understand the physical behavior of ship structures due to impact phenomenon is increasing. In present work, a series of virtual expe

4. Analysis of Structural Crashworthiness and Estimating Safety Limit Accounting for Ship Collisions on Strait Territory
Abstract A series of analyses are carried out to predict the structural crashworthiness of a ship during a collision. The numerical configuration is verified by structural simulations based on a laboratory experiment wherein a penetration test is considered as the experimental reference. Comparative observations of structural behaviour are carefully conducte

5. Crashworthiness Analysis of S-Shaped Structures Under Axial Impact Loading
Abstract To mitigate shock forces in collision events, thin-walled members are used as energy absorber. In this article, crashworthiness of single-cell and multi-cell S-shaped members with various cross-sections including triangular, square, hexagonal, decagon and circular were investigated under axial dynamic loading using finite element code LS-DYNA. Furth

6. Collision-Induced Dissociation Analysis of Brevianamide A and C in Electrospray Ionization Mass Spectrometry
Brevianamides A and C are isomeric cyclic peptides with several reported biological activities, isolated from diverse microorganisms. Currently, there has been no previous investigation of brevianamide fragmentation utilizing electrospray ionization mass spectrometry (ESI-MS). In this work experiments were carried out in the positive mode using two different

7. Studying energy absorption in tapered thick walled tubes
In many engineering structures different energy absorption systems may be used to improve crashworthiness capability of the system and to control damages that may occur in a system during an accident. Therefore, extensive research has been done on the energy-absorbing cells. In this paper, energy absorption in tapered thick walled tubes has been investigated

9. Non-linear FEM analysis of seismic induced pounding between neighbouring multi-storey structures
Pounding of neighbouring construction of structures due to seismic excitation increases the damage of structural components or even causes collapse of structures. Among the possible building damages, earthquake induced pounding has been commonly observed in several earthquakes. Therefore it is imperative to consider pounding effect for structures. This study

10. Estudo sobre a identificação de hádrons em câmaras de fotoemulsão / Study about hadron identification in emulsion chambers
This work introduces the importance of photoemulsion chambers that remain in use after decades and still offer many advantages for elementary particle physics. We cite OPERA (Oscillation Project with Emulsion-tRacking Apparatus) detector that is the greatest lead photoemulsion chamber detector ever constructed as an example of its application nowadays (nine

11. Parametric sensitivity analysis for the helium dimers on a model potential
Potential parameters sensitivity analysis for helium unlike molecules, HeNe, HeAr, HeKr and HeXe is the subject of this work. Number of bound states these rare gas dimers can support, for different angular momentum, will be presented and discussed. The variable phase method, together with the Levinson's theorem, is used to explore the quantum scattering proc
